Abstract
The invention discloses a traveling mechanism for a large-gradient tunnel lining trolley. The mechanism comprises a rail with a central rail, and two groups of power mechanisms, wherein each group of power mechanism is provided with a hydraulic cylinder and a pushing support; one end of the hydraulic cylinder is connected with the lining trolley, and the other end of the hydraulic cylinder is connected with the pushing support; the pushing support is provided with a hook plate; both sides of the central rail of the rail are provided with a plurality of clamping grooves along the length direction; and the hook plate of the pushing support can be separated from the rear clamping groove to enter the front clamping groove under the drive of the hydraulic cylinder, and the hydraulic cylinder can drive the lining trolley to travel when the hook plate of the pushing support falls into the clamping groove. The mechanism has strong power, can avoid the phenomenon that a traveling wheel slips, travels reliably and safely, and can be used in a gradient section with tunnel gradient in the range of 30 degrees.
Description
Technical field
The present invention relates to a kind of running mechanism for the heavy grade tunnel lining trolley.
Background technology
The Sloping Tunnels lining trolley is mainly used in water conservancy and hydropower, the running mechanism of light grade tunnel lining trolley mainly is comprised of motor, chain, walking frame and travelling wheel at present, its operating principle be motor as power source by actuator drives travelling wheels such as chains, this running gear can only use in level land tunnel lining trolley and light grade tunnel lining trolley, when heavy grade uses, the walking of motor-driven travelling wheel, need the more powerful of motor, and frictional force is not enough to provide driving force sometimes, causes travelling wheel to skid.At present in some actual water conservancy and hydropower constructing tunnels, need the heavy grade tunnel lining trolley, the running mechanism of heavy grade tunnel lining trolley mainly is comprised of hoist engine, walking frame and travelling wheel, to be hoist engine take turns work as power source by the actuator drives such as wire rope are out of shape to its operating principle, the heavy grade tunnel lining trolley needs very large driving force, although it is enough that hoist engine is done power source, obviously deficiency has: one, safety is not high, and job security depends on the brake of hoist engine.Two, use not convenient, hoist engine first will be above domatic anchor firm, but anchor firmly will depend on several factors, such as chassis weight, the gradient and rock stratum situation etc., the gradient is larger, its safe and reliable property is just lower.
Summary of the invention
The object of the present invention is to provide a kind of security performance height, smooth running, the easy to operate running mechanism that is used for the heavy grade tunnel lining trolley.
This running mechanism for the heavy grade tunnel lining trolley provided by the invention, comprise the track with central track, actuating unit, described actuating unit has two groups, every group of actuating unit has a hydraulic cylinder, a pushing tow bearing, hydraulic cylinder one end is connected with lining trolley, the other end is connected with the pushing tow bearing, described pushing tow bearing is with hook plate, the central track both sides of track are provided with some draw-in grooves along its length, pushing tow bearing its hook plate under the drive of hydraulic cylinder spins off in can draw-in groove from behind and enters the draw-in groove of front, drives the lining trolley walking when hydraulic cylinder can fall into draw-in groove at the hook plate of pushing tow bearing.
The spacing that each draw-in groove is arranged along the rail length direction equates.Approach switch is equipped with in the front portion of described pushing tow bearing, and a support wheel is housed simultaneously.Displacement transducer is housed above the hydraulic cylinder.
Operating principle of the present invention is: two groups of actuating units have identical structure, their hydraulic cylinder can drive the pushing tow bearing when shrinking makes draw-in groove that its hook plate breaks away from the back move to the draw-in groove of front until fall into the draw-in groove of front, and hydraulic cylinder can drive lining trolley and walk forward when stretching out.But the flexible of the hydraulic cylinder of two actuating units hockets, when the draw-in groove of one group of actuating unit contraction drive pushing tow bearing disengaging back moves forward, the hydraulic cylinder of another group actuating unit stretches out, its pushing tow bearing plays the location in draw-in groove, orientation, hydraulic cylinder stretches out direct promotion lining trolley and walks forward, until hydraulic cylinder stretches out range, transfer again contraction to, the draw-in groove that drives pushing tow bearing disengaging back moves forward, the hydraulic cylinder of first group of actuating unit then stretched out and drove lining trolley and walk forward this moment, made thus steadily forward walking of lining trolley.This shows that work of the present invention is highly stable, simple to operate, and power is powerful, can not produce the phenomenon that road wheel skids.

The specific embodiment
Can find out that from Fig. 1 and Fig. 2 the present invention has guide rail 1 and two groups of actuating units 2.The structure of two groups of actuating units 2 is identical, and hydraulic cylinder 3 and pushing tow bearing 4 are all arranged, and pushing tow bearing 4 is with hook plate 41, one end and the lining trolley of hydraulic cylinder 3 are hinged, and the other end and pushing tow bearing 4 are hinged, and the front end of pushing tow bearing 4 is equipped with support wheel 5, when hydraulic cylinder shrinks, drive pushing tow bearing 4 and move.
From Fig. 3 to Fig. 5, can find out guide rail 1 with central track 11, have some draw-in grooves 12 at the length direction of two edge guide rails of this central track.Pushing tow bearing 4 has hook plate 41, front support guide strip 42, rear support guide strip 43, and pushing tow bearing 4 is seated on the guide rail 1 by front and back support guide plate.The front end of pushing tow bearing 4 is equipped with support wheel 5, and when hydraulic cylinder shrank, pushing tow bearing 4 broke off relations hook plate take support wheel 5 as fulcrum from draw-in groove 12, and in orbit slippage is until enter the draw-in groove of front.One group of contraction of the hydraulic cylinder of two groups of actuating units, another group is then stretched out, and one group of hydraulic cylinder 3 of contraction drives the pushing tow bearing, and one group of hydraulic cylinder, the 3 pushing tow chassis that stretch out simultaneously move forward, when hydraulic jack is retracted to the setting stroke, pushing tow bearing 4 arrives draw-in groove position, front, and hook plate 41 is fallen in the draw-in groove and linked up with, and this oil cylinder begins the conversion direction of motion behind the hook, become by contraction and to stretch out, promote chassis and move forward, this moment, another hydraulic cylinder then began to shrink, and drove the unhook of pushing tow bearing and moved ahead.Two groups of hydraulic cylinder alternating movements make the chassis orbiting.Approach switch 6 is housed on the pushing tow bearing 4, displacement transducer 7 and pressure detection switch 8 are housed on the hydraulic cylinder 21, pressure detection switch 8 detects the stressing conditions of hydraulic cylinders, works under the stressed scope of safety to guarantee it.Displacement transducer 7 guarantees that for detection of the stroke of hydraulic cylinder 2 the action checker of the hydraulic cylinder of two groups of actuating units carries out synchronously, constantly promotes lining trolley and walks forward.Approach switch 6 is surveyed orbital plane in that running gear is in service, fall into smoothly draw-in groove 12 when colluding plate 4, approach switch 7 gets final product work, this moment, system thought that pushing tow bearing 3 realized smooth hook, otherwise, when approach switch 7 can not be monitored orbital plane, system thought that namely walking system realizes breaking off relations smoothly.Running mechanism of the present invention adapts to the slope section of road gradient in highway tunnel in 30 ° of scopes to be used, and has improved to a great extent the safety and reliability of work.
